Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
This means that the rifle sight setting for any range from 0 to 500 meters is available. The sight adjustment procedure can be followed step-by-step. 1. Determine the slant range to the target. Assume that a range finder is available that determines that the target is exactly 300 meters distance. 2. Determine the elevation angle of the target.
Spin rate: faster spin rates will produce more gyroscopic drift because the nose ends up pointing farther to the side. Range, time of flight and trajectory height: gyroscopic drift increases with all of these variables. density of the atmosphere: denser air will increase gyroscopic drift.
The Magnum Rifle was originally offered in .264 Winchester Magnum, and .300 Winchester Magnum. [6] In 1967 the 7 mm Remington Magnum was added to the available chamberings. In 1969 the 7mm Remington Magnum was dropped from production. In 1970 the Magnum Rifle was dropped from the Model 670 lineup entirely.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...

Most rifle cartridges have a high load density with the appropriate powders. Rifle cartridges tend to be bottlenecked, with a wide base narrowing down to a smaller diameter, to hold a light, high-velocity bullet. These cases are designed to hold a large charge of low-density powder, for an even broader pressure curve than a magnum pistol cartridge.
